My daughters friend has a little girl from a previous girlfriend. They were never married. He is listed as the father on the birth certificate. The mother does not want child support and has sole custody of the child. The father paid for the hospital bills when she was born and still pays all her expenses such as health, medical etc. He is very active in her life and has her every weekend and often during the week while the mother works or has a social life outside her home. The mother uses this arrangement to get her way when she wants something. If the father does not jump to her demands, she then threatens to take him to court and ask for child support. He does not even get to claim her on his tax returns period. What are his rights as the father? Can she take this child out of the state (Wisc) without his permission? Should the child become seriously ill, does he has any rights in regards to deciding her treatment or care? If child support was ordered, would he be expected to pay all child support back to the date of her birth even though he has provided support in other ways and this arrangement was agreed upon by both mother and father. Any information would be helpful. Thank you for your help.
